The Badcamp agility test was created to evaluate agility of badminton players. The Badcamp is a valid and reliable test, however, a doubt about the need for the use of this test exists as simpler tests could provide similar information about agility in badminton players. Thus, the aim of this study was to examine the specificity of the Badcamp, comparing the performance of badminton players and athletes from other sports in the Badcamp and the shuttle run agility test (SRAT). Sixty-four young male and female athletes aged between 14 and 16 years participated in the study...

The field of motor expertise in athletes has recently been receiving increasing levels of investigation. However, there has been less investigation of how dynamic changes in behavior and in neural activity as a result of sporting participation might result in superiority for athletes in domain-general cognition. We used a flanker task to investigate conflict-related behavioral measures, such as mean reaction time (RT) and RT variability, in conjunction with electroencephalographic (EEG) measures, including N2d, theta activity power, and inter-trial phase coherence (ITPC)...

Olivier Girard, Franck Brocherie, Grégoire P Millet
Many sport competitions, typically involving the completion of single- (e.g. track-and-field or track cycling events) and multiple-sprint exercises (e.g. team and racquet sports, cycling races), are staged at terrestrial altitudes ranging from 1000 to 2500 m. Our aim was to comprehensively review the current knowledge on the responses to either acute or chronic altitude exposure relevant to single and multiple sprints. Performance of a single sprint is generally not negatively affected by acute exposure to simulated altitude (i...

Clinical Scenario: CrossFit is a form of exercise that incorporates rapid and successive high-intensity, ballistic movements. As CrossFit becomes an increasingly popular fitness option, it is important to determine how rates of injury compare to more traditional forms of exercise. This review was conducted to ascertain the incidence of injury with CrossFit relative to other forms of exercise. Focused Clinical Question: Are injuries more common with CrossFit training than other forms of exercise? Summary of Key Findings The literature was searched for studies that compared injury rates among individuals who participated in CrossFit fitness programs to participants in other exercise programs The search initially yielded >100 results which was narrowed down to three level 2b retrospective cohort studies that was deemed to have met inclusion/exclusion criteria In all three reviewed studies, the reported incidences of injuries associated with CrossFit training programs were comparable or lower than rates of injury in Olympic weightlifting, distance running, track and field, rugby, or gymnastics...

BACKGROUND: Several studies have demonstrated that body habitus is associated with survival (life expectancy) time. We sought to determine if survival differed between elite athletes with a range of body types. We hypothesized that the survival would differ between athlete types and that ectomorph athletes would have longer survival than heavier athletes. METHODS: For each Olympics between 1928 and 1948 we identified the top (up to 20) Olympic male and female finishers in the high jump (HJ), discus throw, marathon, and 100-m run...

Post activation potentiation (PAP) has shown improved performance during movements requiring large muscular power output following contractions under near maximal load conditions. PAP can be described as an acute enhancement of performance or an enhancement of factors determining an explosive sports activity following a preload stimulus. In practice, PAP has been achieved by complex training, which involves a combination of a heavy loaded exercise followed by a biomechanically similar explosive activity, best if specific for a particular sport discipline...
